COGO Points

The name COGO comes from AutoCAD being a COordinate GeOmetry program (COGO). Thus, any point found in any AutoCAD drawing is technically a COGO Point.

Some versions of AutoCAD (Civil 3D included) have the ability to transcribe COGO's and are labeled "point compatible." These objects are custom created by programs like AutoCAD Civil 3D and include information such as, number, Z elevations, and data descriptions.

When a program that is not "point compatible" is used to open a drawing with these custom objects, the result is what are called Proxy Objects.

See our description of Proxy Objects for instructions on removing them from your drawing.
